Broken Access control on Graphs Feature in LibreNMS

LibreNMS is an auto-discovering PHP/MySQL/SNMP based network monitoring which includes support for a wide range of network hardware and operating systems. In affected versions of LibreNMS when a user accesses their device dashboard, one request is sent to `graph.php` to access graphs generated on the particular Device. This request can be accessed by a low privilege user and they can enumerate devices on librenms with their id or hostname. Leveraging this vulnerability a low privilege user can see all devices registered by admin users. This vulnerability has been addressed in commit `489978a923` which has been included in release version 23.11.0. Users are advised to upgrade. There are no known workarounds for this vulnerability.

LibreNMS through 21.10.2 allows XSS via a widget title.

In LibreNMS < 21.3.0, a stored XSS vulnerability was identified in the API Access page due to insufficient sanitization of the $api->description variable. As a result, arbitrary Javascript code can get executed.

A second-order SQL injection issue in Widgets/TopDevicesController.php (aka the Top Devices dashboard widget) of LibreNMS before 21.1.0 allows remote authenticated attackers to execute arbitrary SQL commands via the sort_order parameter against the /ajax/form/widget-settings endpoint.

An issue was discovered in LibreNMS before 1.65.1. It has insufficient access control for normal users because of "'guard' => 'admin'" instead of "'middleware' => ['can:admin']" in routes/web.php.

In LibreNMS before 1.65.1, an authenticated attacker can achieve SQL Injection via the customoid.inc.php device_id POST parameter to ajax_form.php.
